Now the offensive coordinator in San Diego, Whisenhunt was the Titans' head coach when Mettenberger was selected by Tennessee with the No. 178 overall pick in the 2014 NFL Draft. Last offseason, Whisenhunt and his staff reportedly viewed the former LSU star as a poor man's Tom Brady. In other words, a sixth-round pick with a chance to develop into an NFL starter.
Mettenberger offers prototypical pocket quarterback size, a big arm and a willingness to squeeze the ball into tight spaces, but has simply proven incapable of consistently moving the chains through 14 NFL games over two seasons.
His 16.5 Total QBR is the worst of any quarterback with at least 10 starts since the metric was created in 2006. The game film has shown a one-dimensional signal-caller beset by a long delivery, statuesque pocket movement, an inability to handle pressure, slow eyes and scattershot accuracy. His scant NFL success has come primarily on broken coverages and against prevent defenses deep in garbage time.
If he has a chance to turn his career around, though, landing with Whisenhunt in an offensive scheme for which he was drafted is a best-case scenario.
